On the one hand, I wish Boeing had kept upgrading the 757 instead of the 737, as soon as large (high-high-bypass) engines were required, years ago. Those nice long main gear provided more space for growth.....
But I get
tdracer's point.
Plus, with 4500nm range, we are talking trips of up to 10+ hours (especially if low in operating costs (even higher-bypass fans), and environmentally-friendly) - and I'd
really want a bit more elbow-room on flights that long.
Maybe time to revive the old 777-100X "Stubby" concept - the market has had 20-25 years to reconsider the idea.
Sometimes "the customer is always right" - and sometimes the customer is just a 5-year-old tugging on Mommy's arm yelling "I WANT.......!"
